Consider the following economy: Labor supply: Nt= 90 Capital stock: Kt = 90 Government spending: Gt = 20 Tax collections: Tt = 20 Production function: Yt = 2(Kt)0.5 (Nt)0.5 Real money demand Lt = 2Yt - 200rt Consumption function: Ct = 16 + 0.8(Yd)t Domestic price level: Pt = 4 Investment function: It = 25 - 50rt Nominal money supply: Mt = 1296 Plot (a)-(d) on the IS-LM and AD-SRAS-LRAS diagrams. Make sure to label (i) the axes, (ii) the curves and (iii) the initial equilibrium levels.

26. A contractionary monetary policy combined with an expansionary fiscal policy will (A) decrease both income and consumption (B) increase both income and consumption (C) have uncertain effects on the interest rate and investment D) increase the interest rate and decrease investment (E) increase both the interest rate and investment
The money demand function is (M/P)d = Y-150rThe money supply M is 1,000 and the price level P is 2. For this economy, use a graph to illustrate the LM curve for r ranging from 0 to 8.

1. Assume that the GDP of Country A, a commodity exporter, can take on the values of $50, $55, $60, $65, and $70 with equal probability. To smooth consumption, the government of Country A issues $10 government bonds and sell them in the global financial market. If the government default, the costs of default are 25% of GDP. Lenders are competitive and understand these risks fully. a) If the lending rate is 32.5% per annum, what is the country's repayment threshold level of GDP (i.e., the GDP at which it is indifferent between defaulting and repaying the loan)? What is its probability of default? At what GDP level(s) will the country default? b) If the interest rate on safe loans is 6% annum, is the lending rate of 32.5% consistent with the breakeven condition of a competitive lender? Show your answer. c) Assume that the GDP of Country A can now take on the value of $75 (in addition to the five values above) due to higher volatility in commodity prices. Use the consumption-output…

Please pleaseee do this Question : For this question assume that the real money demand function is L(R, Y) = kY - hR where k > 0 represents the sensitivity of the money demand to income and h > 0 represents the sensitivity of the money demand to the interest rate. Suppose that these sensitivity parameters are not known for the economy of Macroland and there are two possibilities: it is either i) high k and low h, or ii) low k and high h. To understand which one of these two scenarios is correct you analyze a given policy change: an increase in the overall level of taxes. Using the AA-DD model, compare and contrast the short run effects of this policy change in Macroland under these two scenarios. Explain your results intuitively.
(b) With the help of an IS-LM diagram, explain the effects of an expected future tax increase on current output, the current interest rate, current aggregate spending. (It’d be better to explain it with diagram, thank you!)
1. Suppose the IS curve is Y = 3945-100i and Y = 1500 + 250i is the LM curve. Using these compute: a) The equilibrium interest rate and output (i*and Y*). b) If government spending was increased by 100m with an immediate impact elasticity of 2.5 in the goods market, determine new income and interest rate. c) Determine the magnitude of the change in money supply required to eliminate any crowding out effect in (c) above. Suppose di/dMs = -0.1X, where X is the last digit of your ID number. d) Explain the dynamics represented in (a-d) using an IS-LM space. (You may insert a snapshot of the graph if drawn manually).

Question Now we introduce banks that will act as liquidity providers in the economy. Suppose that banks are able to issue private IOU's, such that individuals deposit goods with the bank and the bank can promise a return on the deposit. We start by assuming that there is no reserve requirement or lending by the Central Bank. (a) Suppose a young individual wants to use one consumption good to acquire money. What return does the bank need to promise the individual to have them deposit the good with the bank instead? (b) Suppose that when the individual deposits a good with the bank, the bank uses this good to create capital. Further, suppose that when the bank offers a return on deposits that is equal to the real rate of return on money then the individual will choose to deposit with the bank instead of acquiring money. A young individual in period t deposits one good with the bank when young. Suppose no young individuals in period t+1 make deposits. How does the bank pay the young…
